Configure alternate authentication and Office 365 resource URLs

If your organization uses alternate login and Office 365 resource URLs, you must configure the alternate URLs in the app configuration for each required app. For example, the U.S. Government uses alternate login and Office 365 resource URLs. The default URLs are as follows:

  • Login URL: login.microsoftonline.com
  • Office 365 resource URL: outlook.office365.com

The U.S. Government uses the following URLs:

  • Login URL: login.microsoftonline.us
  • Office 365 resource URL: outlook.office365.us

For more information, see the Microsoft resource National clouds.

Note: In addition to configuring the alternate login and Office 365 resource URLs, you must also ensure that your routing and connectivity profiles are configured appropriately and can access the alternate URLs.

Perform these steps on the app configuration of each required app.

  1. In the Office 365 Sign On URL field, type the login URL for your organization.
  2. In the Office 365 Resource field, type the Office 365 resource URL for your organization.
  3. In the Exchange ActiveSync Settings area, in the ActiveSync Serverfield, type the Office 365 resource URL for your organization.
  4. Save the app configuration.
